I am going to go with making a cold brew for 24 hrs and add it right before i bottle. Im going to start with adding a pint of the cold brew and taste it and see if i need more coffee flavor. how many cups of grown coffee and water should i use?

I checked my brewing notes, and here's what I found:

Both times, I used a total of 6 oz of beans. I split them into two batches, so I was putting 3 oz beans in the French press each time (32 oz coffee). For the hot press, I let it steep for 10 minutes and added it at bottling. I did preboil the water first for 5 min to force out oxygen.

On the second batch, I used the same amount of beans (2 batches through the press @ 3 oz beans in each batch). But for the cold press, I let the beans steep for 10-12 hours on each batch.

What I found is that the cold press method produced a lot stronger coffee flavor, so I would scale back the amount of beans when doing a cold press. Maybe cut the amount down to 3-4 oz for the batch.
